STORAGE STRUCTURE.

SPECIFICATION forming part of Letters Patent N o. 716,296, dated December 16, 1902.

Application filed April 26, 1902. Serial No. 104,900. (No model.)

` zen of the United States of America, residing in Bradford, in the State of Rhode Island,have

`invented Improvements in Storage Structures, of which the followingis a specification.

My invention relates to that class of structures which are employed for the storage of coal and other granular material and in which the floor of the storage-space slopes off in opposite directions from a i central line or is A-shaped, as it is commonly termed. In such structures the coal or other granular material is received into storage from above and can be delivered through openings along the side walls or through chutes in the floor near the sides. The angle of the sloping floor may be more orless than the angle of the fric- `tion of the material to be withdrawn; but it tendency to distortion arising when only one sideof the storage-space is loaded.

In the accompanying drawings, Figure lis a diagrammatic vertical section on the line l l, Fig. 2, of such a building embodying my i invention; and Fig. 2 is asectional plan on the line 2 2, Fig.` l.

In the views, S S are the vertical side walls of the structure, and B B arethe end or cross walls, and F F represent the A-shaped iioior.

Y The roof R may be of any suitable character; but in the drawings I have shown it as sloping in opposite directions from a center line in correspondence with the slopes of the floor F.

If both sides of the building or bin are equally loaded with the stored material, the outward pull of one side wall will balance the outward strain on the other; but if one side only is-loaded there will be a great tendency to distortion set up. To meet this difculty, I combine with and tie up to the side walls one or more longitudinal backbone-trusses, which I anchor to the end or cross Walls. The exact location of such backbone truss or trusses may vary as convenience may dictate. One such truss will generally suffice, and in such case it should be arranged centrally between and parallel with the side walls. In the construction shown in the drawings this backbone-truss may be conveniently located along the center, near the top, as shown at T, and tied to the side walls S S by the ties V V. It is preferable to have the plane of the backbone-truss horizontal, as is shown at T in Fig. l.

If the structure is relatively long, it may be preferable to provide substantially cross frames or walls, as at B', Fig. 2, intermediate of the end walls.

I claim as my inventionl. A structure for storing granular material, said structure being 'an A-shaped floor with side and end walls and a longitudinal truss anchored to the cross-walls and ties connecting the side walls of the said truss, as and for the purpose described.

2. A structure for storing granular material, said structure being an A-shaped floor with side and end walls and also cross frames or walls and a longitudinal backbone-truss lying in a horizontal plane and ties connecting the side walls to said truss, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

AUGUSTUS SMITH.
